Special Issue Information

Dear Colleagues,

A global rise in population and increased urbanization have resulted in growing pressure on freshwater resources. Known and unknown organic pollutants have exacerbated water stress and water risk throughout the world. Furthermore, their transformation products are potentially harmful to the environment. A good understanding of the cause, fate and hazards of these new organic pollutants should be considered as part of the sustainable solution to the ongoing water crisis. Improving sensitive analytical methods is vital to accurately measuring these pollutants’ levels in various water matrices. Global research focusing on the prevention and treatment of organic pollution is ongoing, particularly studies on improving water monitoring, non-target screening, the use of mathematical and machine learning modeling for source identification or pollution prediction and the assessment of ecological and health risk.

The present Special Issue intends to bring together recent research exploring the potential of advanced technologies for the analysis and assessment of new organic pollutants. Fundamental and applied research covering multidisciplinary topics, as well as review papers focusing on relevant topics, are welcome. Topics of interest includes, but are not limited to, the following:

  • Analysis and the fate of emerging contaminants.
  • Source identification of new organic pollutants.
  • Occurrence of new organic pollutants in non-conventional water resources (e.g., rainwater and seawater).
  • Mathematical and machine learning modeling.
  • Applications of deep learning techniques in new organic pollutant monitoring and predictions.
  • Ecological and health risk
  • (Eco)toxicity assessment of new organic pollutants.
  • Targeted strategies for the management and prevention of pollution.
  • Engineering applications of innovative water treatments.

Jiangsu High-Tech Fluorochemical Industrial Park in Changshu City, Jiangsu Province, is the largest fluorochemical industrial park in Asia. The occurrence of per- and polyfluoroalkyl substances (PFASs) in surface water and widespread local plants was investigated in Jiangsu High-Tech Fluorochemical Industrial Park. Thirty-two target PFASs were detected in dissolved-phase, particle-phase and plant samples. The concentrations of total PFASs ranged from 1650 to 8250 ng/L in the dissolved-phase samples, 132 to 6810 ng/g dw in the particle-phase samples and 25.8 to 9460 ng/g dw in different plant tissues. Perfluorohexanoic acid (PFHxA), Perfluorooctanoate acid (PFOA) and 6:2 fluorotelomer carboxylic acid (6:2 FTCA) were predominant PFASs and contributed 80−91% to ΣPFAS in water samples. A total of 67 emerging PFAS were identified in all samples using nontargeted analysis. Typha orientalis showed better accumulation ability, with an average ΣPFAS concentration of 3450 ng/g dw and the highest root concentration factor (RCF) of 171. Typha orientalis, Eichhornia crassipes and Alternanthera sessilis have potential for use in PFAS phytostabilization. Full article
